I have been having some discussion with some people and it was bugging me so I thought I could get some experienced opinions out here.
Firstly, I always thought a higher octance rating gave an extra boost for pickup. The reason for this thought is that when I had a toyota camry for a yr before my bmw, although it was a 4 cylinder, I could actually tell the difference in pickup when I put 89 octane and 93 octane. However, now after some friends pointed out and did some research online, it claims no difference in performance unless you change the compression ratio. Is this always true cuz I could swear I could tell a difference.
Secondly, one of my friends claims that fancy rims actually hinder performance negligibly. He says that the normal simple rims which fit hubcaps on them provide the best mass distribution and BMW and all the "good" car companies just put rims cuz they look good. My claim is that they looks are a part of it , but I do not believe under any means that they hinder performance.
Some advice to get me good sleep at night will be highly appreciated. Thanks
